Do you need help identifying a 🌶?
Is your plant suffering from an unknown issue? 🤧
Then ask in Identification and Diagnosis.

You've got pests, your answer is to spray/drench with neem oil or your choice of pesticide and do it soon.ragga said:

Need some details... What have you been applying to these plants? Nutrients, pesticides, etc.

When posting questions, give as much detail as possible. If you don't know all of the right things to include, at least give as much as you know to ask.
Okay the fertilizers I'm using is Medina Hasta Pro Plant,Miracle Pro,Epsom salt,Bio-Live and Cal-Mag is all I've been using all year and this just started happening two weeks ago,i'm lost trying to find solutions, maybe a fertilizer not sure at allium in Houston and it's very hot every day 98 degrees and above.
How much of that stuff? Cause I'm not gonna lie, this looks an overfeeding problem.
.
Forget what you hear on this and other forums, about magic formulas. Drop the damn epsom salt cold. You don't need it (like I doubt that you will literally EVER need it). Cal/Mag? It's highly doubtful that you need it. But it doesn't need to be added, "just because".
.
The last of your "good" leaves look thick and brittle. In my opinion, it looks like you gradually worked up to overfed. When I started out in hydro, I was guilty AF of overfeeding. This looks very much like problems that I experienced.
.
A second and equally valid concern - with temps like that, you may have fed too much, while also having a watering issue. Again, this is reminiscent of warm reservoir temps in hydro. This can be mimicked by warm temps, and waterlogged media (i.e., no nutrient uptake, waterlogged, no oxygen in root zone) Tell me about your watering habits. Tell me what your plants are potted in. (the mix)
.
What should be sought for: A basic grow, using only a complete nutrient, on the prescribed feeding cycle (per the instructions). All of the other products need to be shelved, until/unless the grow calls for it. Peppers grow amazingly well with a minimum of "stuff" and "love". I would love to get you there.

Well, disregard my first post as I didn't realize you sprayed with ferrous sulfate solution that could cause what we're seeing, maybe..?
I'd go with whatever S7 says...
ferrous sulfate

Well, don't speak that language, sorry. But a google translate search came up with this stuff, that I assume you sprayed for fungus problems..?evolka said:
ferrous sulfate
Disadvantages of:
- do not spray on leaves and young growths - ferrous sulfate burns them in a concentration of more than 1%
- concentration up to 1% - practically ineffective for the pathogen
- ferrous sulfate is rapidly oxidized to ferric iron and loses its fungicidal properties
- therefore, the period of protective action is on average only 10-14 days
- it must be processed very carefully in the spring, it is advisable to use only in the fall
Well as long as you asked, S7 explains it perfectly, Below is a quote from S7...evolka said:
Yes, I already noticed
I asked how do you make a neem spray concentration for plants
"In a small container - I personally use a 1 cup Pyrex mixing cup - add about 1/4-1/2 cup water. To this, add 2 Tbsp Neem, and 1 Tbsp soap. Mix it together until the soap has completely emulsified the oil. (stir it - I use the dosing spoon, so that I don't waste) Then, gradually pour this into 2 gallons of water in the sprayer (if you're going to do foliar) or the watering can. (if you're going to drench)
I might advise you to test a small area of your plant first, if you haven't done this. You may find that the pH is too high. If that's the case, squeeze a half lemon into the whole thing. Shake well. Spray/drench."
"shake the ever livin' shit out of the mixture in the sprayer, with the top in place"
I use his exact recipe and have had great results.
My 2cents, when its time to clean your sprayer, if you see globules at the bottom of your sprayer when you're done you've not shaken it enough and or emulsified it properly. This means your mix was not consistent and weaker than it should have been...
Warm almost hot water helps emulsify the oil with soap. I use cold pressed pure neem oil and Dr Boners peppermint soap.
